Hello,

In a SharePoint 2010 to SharePoint 2016 migration project I was recently involved in, I noticed that in the new SharePoint 2016 Portal, the logo URL in all sites was pointing to an invalid URL.

The Problem

The reason for this is that the Logo URL was pointing to a URL in the SharePoint hive (_layouts virtual directory) and the _layouts virtual directory URL has changed from SharePoint 2010 to SharePoint 2016:

  • SharePoint 2010 Layouts root virtual directory URL: /_layouts
  • SharePoint 2016 Layouts root virtual directory URL: /_layouts/15

The Solution

Since the site collection has a lot of subsites and I would like to avoid having to change the logo URL manually one by one, I built a small PowerShell script that will loop all the sub sites in the site collection and change the Logo URL for each one. Here is the script:

$sitelogo = "/_layouts/15/Images/logo.jpg"

$site = "https://intranet"

$sites = new-object Microsoft.SharePoint.SPSite($site)

foreach ($web in $sites.Allwebs) {

$webUrl = $web.Url

"Changing site logo url at $webUrl"

$web.SiteLogoUrl = $sitelogo

$web.Update()

}

$sites.Dispose()

NOTE: This script should also be valid for SharePoint 2013 and SharePoint 2019.

Hope this helps!
